The logic is also configured to cause the processing circuit to perform, by the first host, at least one action selected from a group of actions in response to the indication by the application and data security policy to perform the one or more actions, the group of actions including allow-and-analyze, drop-and-analyze, and mirror.

FIELD OF THE INVENTION

The present invention relates to network and system protection, and more particularly, this invention relates to a dynamic mirroring mechanism based on data socket descriptors and use thereof for security analytics.

BACKGROUND

Some conventional switches provide a feature for flow-based mirroring where a network administrator may enable a mirroring mechanism based on switch ports. For the purpose of debugging protocol interactions and understanding traffic patterns, mirroring is widely used. In some cases, by mirroring or replicating flows, effective problem replication may be performed for problem investigations. Here, problems may be of various natures. However, an application has no control over the mirroring functionality for its own flows in and out of a server. Secondly, today's mirroring mechanisms cause a performance impact on all other applications and application flows. Currently, there is no intelligence available to mirror packets based on application states without impacting other applications or application flows.

Applications are made up of a large number of instructions and data. Instructions operate on data which is fetched in a cache and memory and is always unencrypted. Scaled-out, distributed applications are made up of a large number of application instances. These application instances have their own data in the cache and memory of the processor on which these applications run. A large number of such application instances communicate with each other and process data in parallel to create an aggregate output.

These types of scaled-out applications are extremely vulnerable to application breaches, data thefts from cache and memory by scraping, and other methods of illicitly obtaining data from the applications, cache, and/or memory. Therefore, mirroring may be a useful mechanism for identifying possible threats, but not with the limitations of current mirroring mechanisms.

SUMMARY

In one embodiment, a method includes receiving, at a first host on which an application instance is operating, an application or data security policy for a first data socket descriptor indicating to perform one or more actions including to mirror one or more payloads received or transmitted by the first data socket descriptor of the application instance. The method also includes performing, by the first host, at least one action selected from a group of actions in response to the indication by the application and data security policy to perform the one or more actions. The group of actions includes allow-and-analyze, drop-and-analyze, and mirror.

According to another embodiment, a system includes a processing circuit and logic integrated with and/or executable by the processing circuit. The logic is configured to cause the processing circuit to receive, at a first host on which an application instance is operating, an application or data security policy for a first data socket descriptor indicating to perform one or more actions including to mirror one or more payloads received or transmitted by the first data socket descriptor of the application instance. The logic is also configured to cause the processing circuit to perform, by the first host, at least one action selected from a group of actions in response to the indication by the application and data security policy to perform the one or more actions, the group of actions including allow-and-analyze, drop-and-analyze, and mirror.

In yet another embodiment, a computer program product includes a computer readable storage medium having program instructions stored thereon. The program instructions are executable by a processing circuit to cause the processing circuit to receive, at a first host on which an application instance is operating, an application or data security policy for a first data socket descriptor indicating to perform one or more actions including to mirror one or more payloads received or transmitted by the first data socket descriptor of the application instance. The program instructions also cause the processing circuit to perform, by the first host, at least one action selected from a group of actions in response to the indication by the application and data security policy to perform the one or more actions, the group of actions including allow-and-analyze, drop-and-analyze, and mirror.

FIG. 1 illustrates an architecture 100, in accordance with one embodiment. As an option, the present architecture 100 may be implemented in conjunction with features from any other embodiment listed herein, such as those described with reference to the other figures. Of course, however, such architecture 100 and others presented herein may be used in various applications and/or in permutations which may or may not be specifically described in the illustrative embodiments listed herein. Further, the architecture 100 presented herein may be used in any desired environment.

As shown in FIG. 1, a plurality of remote networks are provided including a first remote network 104 and a second remote network 106. A gateway 102 may be coupled between the remote networks 104, 106 arid a proximate network 108. In the context of the present network architecture 100, the networks 104, 106 may each take any form including, but riot limited to, a LAN, a WAN such as the Internet, a storage area network (SAN), a public switched telephone network (PSTN), an internal telephone network, etc. Additional networks 110, 112 may also be connected via the gateway 102 or some other connection device known in the art. These networks may be of a different type than the networks 104, 106. For example, network no may be a network devoted to the IOT, and may provide infrastructure and protocols for communication between all devices in the IOT, and between any devices in the IOT and the networks 104,106. In another example, network 112 may be a network devoted to Industrial control, and may provide infrastructure and protocols for communication within and/or between facilities anywhere in the world, including automated devices, manufacturing lines, assembly lines, processing control software, etc.

In use, the gateway 102 serves as an entrance point from the remote networks 104, 106 to the proximate network 108. As such, the gateway 102 may function as a router, which is capable of directing a given packet of data that arrives at the gateway 102, and a switch, which furnishes the actual path in and out of the gateway 102 for a given packet.

Further included in the network architecture too is at least one data server 114 coupled to the proximate network 108, and which is accessible from the remote networks 104, 106 via the gateway 102. It should be noted that the data server(s) 114 may include any type of computing device/groupware. Coupled to each data server 114 is a plurality of user devices 116.

According to some approaches, methods arid systems described herein may be implemented with and/or utilized on virtual systems and/or systems which emulate one or more other systems, such as a UNIX system which emulates a MAC OS environment, a UNIX system which virtually hosts a MICROSOFT WINDOWS environment, a MICROSOFT WINDOWS system which emulates a MAC OS environment, etc. This virtualization and/or emulation may be enhanced through the use of virtualization software, such as VMWARE ESX, MICROSOFT HYPER-V, SIMICS, etc., in some embodiments.

In more approaches, one or more of the networks 104, 106, 108, 110, 112 may represent a cluster of systems commonly referred to as a “cloud.” In cloud computing, shared resources, such as processing power, peripherals, software, data processing, servers, storage, etc., are provided to any system that has access to the cloud and permission to access the specific resource, preferably in an on-demand relationship, thereby allowing access and distribution of services across many computing systems. Cloud computing typically involves an Internet or other high speed connection (e.g., 4G LTE, fiber optic, etc.) between the systems operating in the cloud, but other techniques of connecting the systems may also be used as would be understood by those of skill in the art.

FIG. 2 shows a representative hardware environment associated with a user device 116 and/or a server 114 of FIG. 1, in accordance with one embodiment. FIG. 2 illustrates a typical hardware configuration of a workstation 200 having a central processing unit 202, such as a microprocessor, and a number of other units interconnected via a system bus 204.

The workstation 200 shown in FIG. 2 includes a Random Access Memory (RAM) 214, Read Only Memory (RUM) 216, an I/O adapter 218 configured to connect peripheral devices, such as disk storage units 220 to the bus 204, a user interface adapter 222 configured to connect a keyboard 224, a mouse 226, a speaker 228, a microphone 230, and/or other user interface devices such as a touch screen, a digital camera, etc., (riot shown) to the bus 204, communication adapter 210 configured to connect the workstation 200 to a communication network 206 (e.g., a data processing network) and a display adapter 212 configured to connect the bus 204 to a display device 208.

The workstation 200 may have resident thereon an operating system, such as the MICROSOFT WINDOWS Operating System (OS), a MAC OS, a UNIX OS, etc. It will be appreciated that a preferred embodiment may also be implemented on platforms and operating systems other than those specifically mentioned herein. A preferred embodiment may be written using JAVA, XML, C, and/or C++ language, SCALA, COBOL, FORTRAN, or other programming languages, along with an object oriented programming methodology or scripting language such as PERL, PYTHON, Tcl/Tk, or other scripting languages. Object oriented programming (OOP), which has become increasingly used to develop complex applications, may also be used.

Moreover, one or more hardware processors may be implemented in a processing circuit in the workstation 200. The processing circuit includes the one or more hardware processors, along with any connections or links therebetween necessary to interconnect the one or more processors in the processing circuit. In addition, the processing circuit may be implemented with logic and/or may be configured to execute logic, with the logic being configured to cause the processing circuit to perform functionality specified by the logic.

Now referring to FIG. 3, a logical representation of an application instance 306 operating on a computing system 300 is shown according to one embodiment. Although only one application instance 306 and one set of data 308 is shown in FIG. 3, as would be understood by one of skill in the art, any number of application instances and groups of data may be hosted on a computing system 300, limited only by the processing power and/or other resources available to the computing system 300.

As shown in FIG. 3, an application protection layer (APL) 302 and a data protection layer (DPL) 304 are represented within the computing system 300, according to one embodiment. The application instance 306 has access to data 308 within the computing system 300. Also, the application instance 306, through any number of standard and/or custom APIs, may utilize any of a plurality of data socket descriptors (e.g., data socket descriptor #0 312, data socket descriptor #1 314, data socket descriptor #2 316, . . . , data socket descriptor #N 318) with which to communicate (send and/or receive) information outside of the application instance 306 or computing system 300. One or more server base sockets 310 is provided in the application instance 306 of computing system 300 arid is used for control of the peer application instances on the computing system 300, outside the system, or outside the application instance 306 itself, as would be understood by one of skill in the art.

In order to provide application and data protection to application instances of distributed, scaled-out applications which have instances operating on a plurality of computing systems, at least two operations may be performed, and are described below according to one embodiment.

In a first operation, application instances, such as application instance 306, are identified based upon data socket descriptor attributes that an application instance uses to communicate between other application instances and/or group(s) of application instances on/or outside of the computing system 300. For example, in response to application instance 306 utilizing data socket descriptor #0 312 consistently to communicate with another system, an association may be established between data socket descriptor #0 312 and the application instance 306. By consistently, what is meant is that application instance 306 utilizes data socket descriptor #0 312 to communicate with another system more than a predetermined number of times within a given period of time, according to one embodiment. In another embodiment, consistently utilizing a data socket descriptor means that only a specific data socket descriptor is used in exclusion of all others over a given period of time.

In a second operation, a group is formed which includes any application instance which has all of the same socket descriptor attributes (or at least a predetermined amount of the same socket descriptor attributes, or the same of a certain group of socket descriptor attributes), e.g., data exchange sockets of the same application base socket, transport protocol, server port, various multi-tenancy characteristics, storage characteristics, payload sizes, container attributes, and/or multiple time contexts are grouped together.

Any socket descriptor attributes may be considered when determining whether an application instance shares data socket descriptor attributes with another application instance, such as OS arid container attributes which include server port, transport protocol, network address translation (NAT) IP address range, maximum transmission unit (MTU), application payload sizes, user programmable attributes such as multi-tenancy labels etc.

Using the above two operations, two layers of protection (application protection arid data protection) are enacted together to protect the application (not shown) from which the application instance 306 is provided and any group of application instances related to the application that provides the application instance 306.

FIG. 3 shows the Application and Data Protection Layer (ADPL) libraries which keep track of the server base socket 310 and various data socket descriptors 312, 314, 316, . . . , 318 opened by an application instance 306 for communication of data with one or more peer applications outside of the computing system 300. The data socket descriptors 312, 314, 316, . . . , 318 are used for the exchange of data with another system outside of the computing system 300.

The data socket descriptors 312, 314, 316, . . . , 318 are numbers that represent attributes and/or characteristics of different data exchanges between the application instance and one or more receiver hosts. Each data socket descriptors 312, 314, 316, . . . , 318 may have a size ranging from 12 to 48 bits, such as 32 bits in one embodiment.

Each of the Application Protection Layer (APL) 302 and the Data Protection Layer (DPL) 304 utilize individual sets of application programming interfaces (APIs) that are configured to piggyback on existing APIs, but add specialized functionality to any action performed using the existing APIs.

These new socket APIs and data protection APIs, and the type of application payload sent and received, do not disturb the intermediate security appliances such as firewall, Intrusion Prevention and Intrusion Detection, etc.

The APL 302 provided by the ADPL APIs enables the application instance 306 to have functionality for opening base sockets, opening session-based data socket descriptors, and mirroring the data socket descriptors. These ADPL APIs are layers of APIs built around the operating system library. Apart from standard data socket functionality, these ADPL APIs provide additional functionality of data socket descriptor mirroring, managing original data socket descriptors, arid mirroring data socket descriptor sessions.

The application instance 306 utilizes the one or more server base socket(s) 310 with standard and/or private well-known port number(s) as a control socket, but opens a new data socket descriptor and allocates a different port number to the new data socket descriptor in order to handle actual functionality and data transfer between the computing system 300 and any other external or peer system. The application instance 306 utilizes the new data socket descriptors for control sessions with peer applications.

Once the control session agrees to establish communications, a separate data socket descriptor is assigned to the session for actual data transfer or interaction functionality between the peers, i.e., the server and the originator. The new data sockets and their data socket descriptors have different attributes than the base socket, but they follow the same transport layer protocol. There may be as many as 2048 session socket descriptors for a base socket.

Data socket descriptors are file descriptors assigned to offloaded data sockets for actual data transfer between two end points. This mechanism applies more to transmission control protocol (TCP) sockets than user datagram protocol (UDP) sockets. However, data socket mirroring functionality is provided to UDP sockets as well as to TCP sockets.

The server base socket 310 has the following attributes and/or characteristics:

-   -   1. A server and/or a source internet protocol (IP) interface.     -   2. A standard and/or known server port number, e.g.,         transmission control protocol (TCP) port, user datagram protocol         (UDP) port, etc.     -   3. A maximum number of allowable waiting connections.     -   4. A maximum (and possibly minimum) application packet buffer         size usable for transmitting and receiving data.     -   5. Other socket options provided by the operating system, the         user, or an external input.

The above described attributes and/or characteristics may also be attributed to the plurality of allocated data socket descriptors 312, 314, 316, . . . , 318. When a connection is established between the computing system 300 and another system via the application instance 306, a data socket descriptor is allocated. The allocated data socket descriptor has the following attributes and/or characteristics:

-   -   1. A server and/or a source IP interface.     -   2. A standard and/or known server port number, e.g., TCP port,         UDP port, etc.     -   3. A maximum number of allowable waiting connections.     -   4. Application packet buffer size for transmit and receive.     -   5. A port number of the transport of the allocated data socket         descriptor (in the computing system 300).     -   6. An IP address of the peer data socket descriptor (in an         external system) of the allocated data socket descriptor         (usually, but not always, in TCP sockets).     -   7. A port number of the transport of the peer data socket         descriptor of the allocated data socket descriptor in all cases         of controlled port allocations by the application instance 306.     -   8. A maximum (and possibly minimum) application packet buffer         size usable for transmitting data to and receiving data from         (transmissions with) the peer data socket descriptor.

Apart from the above described characteristics and/or attributes, additional characteristics that may be attributable to an allocated data socket descriptor include:

-   -   9. A first identifier (ID₁): a globally unique identification         number given for an entity (such as an enterprise, company,         university, city subdivision, etc.) that utilizes the ADPL         mechanism in the application instances or programmed for         proprietary purposes     -   10. A second ID (ID₂): a unique identification number within the         entity (not necessarily globally unique). Each ID₂ represents a         subdivision within the entity, such as an individual business         unit within an enterprise, a water district within a city, etc.,         or programmed for proprietary purposes.     -   11. Secure base signature: a base signature or scrambled         alphanumeric or numerical code used in the generation of         signatures per data socket descriptor.     -   12. Secure runtime signature: a scrambled alphanumeric or         numerical code used as a signature on a per data socket         descriptor basis.     -   13. Application name: a name given to the application instance         operating on the computing system.     -   14. Application ID: an identification number provided to the         application instance operating on the computing system.     -   15. Process ID: an identification number provided to a         particular process which is accountable for the data.     -   16. Server port: the particular port on the server on which data         is received or sent.     -   17. Transport protocol: the particular transport protocol used         to send data.     -   18. Base Crypto Version: the version of the cryptographic         process used to encrypt data.     -   19. Co-Lo Need: Co-locationing criterions where applications or         application instances may reside together in the same server,         server pool, rack, pod, or data center.     -   20. Architecture Tier: a tier within the system architecture on         which the (web, application, database, etc.) operates.     -   21. Storage Attachments: an attribute that describes how the         storage is attached to the computing system (e.g., direct,         network, distributed, etc.)     -   22. Proprietary Multi-Tenant Label: a label within the ADPL tag         which designates some information selectable by the user.

These unique attributes when combined together in one of many different variations, are able to identify a data socket descriptor, and locks that data socket descriptor to one particular instance of a scaled-out application group.

In one embodiment, data socket descriptor-based mirroring may De performed intelligently for precisely required states of applications or application instances operating on servers in a data center. Moreover, data socket descriptor-based mirroring may be performed for an exact number of packets or payloads to catch an identified symptom. These actions are riot capable of being performed using conventional mirroring mechanisms. On top of the lack of precision, current approaches examine every packet or payload belonging to all the servers in the data center segment where the network switch performs port-based mirroring. This requirement adds a performance penalty since every packet or payload must be examined in order to minor the specific flow.

Therefore, the data socket descriptor-based mirroring mechanism operates at a level that enables such desirable functionality. It also provides complete flexibility and programmability to control mirroring from the applications and application instances as well as via external policies for a particular data socket descriptor.

While mirroring data socket descriptors, any or all of the above described attributes may be used to selectively mirror packets or payloads being sent over the data socket.

Now referring to FIG. 4A, normal data socket descriptor functionality 400 is shown between multiple application or application instances during data transfer, according to one embodiment. Application Instance #0 402 a utilizes data socket descriptors 404 a #0, #1, #2, . . . , #N. Application Instance #1 402 b communicates with data socket descriptor #0 on Application Instance #0 402 a via data socket descriptor #0 404 b. Application Instance #2 402 c communicates with data socket descriptor #1 on Application Instance #0 402 a via data socket descriptor #1 404 c. Application Instance #3 402 d communicates with data socket descriptor #2 on Application Instance #0 402 a via data socket descriptor #2 404 d.

As shown in FIG. 4B, to perform mirroring functionality 450, standard socket APIs are modified and/or additional functionality is added around standard socket APIs.

Mirroring may take place as ingress payload mirroring or as egress payload mirroring. For egress payload mirroring, the application buffer and metadata associated with the application buffer and/or mirroring operation is copied and sent. As shown in FIG. 4B, mirrored data socket descriptors #0-N are copied as mirroring data socket descriptors Mo-MN. The application buffer and metadata is sent in UDP/IP or TCP/IP transport packets.

The mirrored data socket is the data socket descriptor which receives (on the ingress side) or transmits (on the egress side) the packet or payload. This mirrored data socket descriptor #0 408 a is copied as data socket descriptor Mo 408 b and is sent to an analytics server 406 as DSD Mo 410 for analysis, tracking, etc. The mirroring data socket descriptor Mo 408 b connects Application Instance #0 402 a to the analytics server 406 using UDP or TCP protocol. Moreover, analytics application descriptors (e.g., DSD Mo 410) are descriptors which receive mirrored payloads and associated metadata on the analytics application(s) operating on the analytics server 406.

The new APIs and mechanism manage the mirrored data socket descriptors (e.g., DSD #0 408 a) and mirroring data socket descriptors (e.g., DSD Mo 408 b). The mirrored payload is in the form of metadata and a payload. The metadata comprises an original source, destination port and/or address, source port and/or address, time stamp, base server port, and other details of the payload. As per the policies or configuration, the associated mirroring data socket is identified for this payload on the source data socket descriptor. Together with metadata identifying this payload and mirroring arrangement, the payload is sent to the peer end of the mirroring data socket descriptor (Application Instance #1 402 b). One or more mirrored data socket descriptors may be mirrored as one or more mirroring data socket descriptors in various embodiments. Moreover, any mirrored payloads including metadata and the payload may be sent to the analytics server 406 for analysis, tracking, etc.

Now referring to FIG. 5, the ADPL architecture 500 is shown according to one embodiment. A shared memory interface 502 (also referred to as a message queue) is used by inter-process communications (IPC) for multiple process communications, including messaging, using a memory 504, which may be a shared memory in one embodiment. The shared memory interface 502 is used to send and receive configuration and data between the management process 506 and ADPL libraries (target applications) 510. The size of the memory 504 is set to be of a size to ensure optimum messaging performance.

The logging interface 508 utilizes the management process 506 on one side and the ADPL 510 on the other side. The management process 506 is a message multiplexer in one embodiment. Moreover, the management process 506 may De an independent module, thread, and/or process created when the first application instance using the ADPL 510 is spawned. The application instance calls an ADPL socket API for communication with other entities. The ADPL API checks for the presence of the management process 506. In response to a determination that the process exists, the ADPL API registers itself with the management process 506 along with all its associated and/or requested attributes. During run time, the ADPL API registers each data socket descriptor opened for communication in the Socket Descriptor Database 514 kept with the application instance by the ADPL API. The Socket Descriptor Database 514 includes a list of all registered data sockets with associated data socket descriptors, DIP, base keys, and a latest key for transmission. Policy functions may be added, deleted, modified, and searched within the Socket Descriptor Database 514.

The management process 506 may be configured to perform and/or maintain the following functionality:

-   -   1. Track existing and new application instances on the server         including their individual communication sessions at the base         socket level and at the data socket descriptor level in both         discovery-only mode and in protection mode.     -   2. Store a list of the latest and/or most active applications         that utilize ADPL in protection mode, and applications that         utilize ADPL in discovery-only mode.     -   3. Perform configuration management including forwarding         configuration messages and other messages between the ADPL and         the policy orchestrator.     -   4. Perform application health checks and monitor the health of         registered applications that utilize ADPL in protection mode.

In addition, the Application Database 518 within the management process 506 is configured to have a list of registered applications stored therein based on data socket descriptor discovery.

The management process 506 is configured to utilize all the application registry data to provide the application tracking function. Every time a new application or data socket is registered, details/attributes of the new application and/or data socket are provided to the policy orchestrator that is configured to control the configuration and details of each individual application instance. The socket descriptor details provided by the management process 506 from individual servers help the policy orchestrator to group all the data socket descriptors and application instances together to form a larger picture of all the applications running across the data center, also referred to as application visualization.

The management process 506 is also configured to communicate with the policy orchestrator, which in turn provides policy related configuration to the management process 506 to be applied to individual data socket descriptors of the application instance. On the other hand, the management process 506 communicates with the application instance and provides the application instance with the configuration.

The management process 506 is also configured to check the health of application instances via health check messages, among other mechanisms. This health check information in run-time may be used to keep track of the health of each individual application instance, especially the application process status. Using this information for application performance, distribution of workloads and trouble-shooting of the scaled out application is possible.

The Security Policies Database 512 includes hash-based keys for each policy. The Socket Descriptor Database 514 includes a list of all registered data sockets with associated data socket descriptors, DIP, base keys, and a latest key for transmission. The packet options processor 516 is configured to provide packet processing, and may include some or all of the following functionality: packet receive processing, reading data socket options, keys processing per security policies, security profile processing per security policies, finding violations and updating keys, and updating logs.
